The intense red color of $\left[\mathrm{Fe}(\mathrm{bpy})_{3}\right]^{2+}$ (bpy $=2$,2' -bipyridine) is due to)
(a)metal-to-ligand charge transfer (MLCT)
(b)ligand-to-metal charge transfer (LMCT)
(c)d-d transition
(d)inter-valence charge transfer (IVCT)
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
